Core and Builtins
-----------------
- Issue #6780: fix starts/endswith error message to mention that tuples are
accepted too.
- Issue #5057: fix a bug in the peepholer that led to non-portable pyc files
between narrow and wide builds while optimizing BINARY_SUBSCR on non-BMP
chars (e.g. "\U00012345"[0]).
